How to get cpu's physical ID in C++ - 在C++中如何获取CPU物理ID

CString CStaticPubFunc::GetCPUPhysicalSerialNo()
{
	unsigned long ulS1,ulS2;
	CString strCPUID,strCPUID1,strCPUID2;
	__asm
	{
		mov eax,01h
		xor edx,edx
		cpuid
		mov ulS1,edx
		mov ulS2,eax
	}
	strCPUID1.Format("%08X%08X",ulS1,ulS2);
	__asm
	{
		mov eax,03h
		xor ecx,ecx
		xor edx,edx
		cpuid
		mov ulS1,edx
		mov ulS2,ecx
	}
	strCPUID2.Format("%08X%08X",ulS1,ulS2);

	strCPUID = strCPUID1 + strCPUID2;

	return strCPUID;
